Automation
New in SPM 8.0: 65 Pre-packaged scenarios, basically experiments, inspired by how leading model analysts structure their work. We call them "Automates." These "Automates" or experiments create multiple models automatically so that the analyst can easily see choices.
Example 1: Banking Applications
Automate Shaving
Automate Shaving helps to identify subsets of informative data within large datasets containing correlated variables within the account data. With automation, you may accomplish significant model reduction with minimal (if any) sacrifice to model accuracy. For example, start with a complete list of variables, and run automated shaving from the top to eliminate variables that look promising on the learn sample but fail to generalize. Later you can run shaving from the bottom to automatically eliminate a major bulk of redundant and unnecessary predictors. Then follow up with "shaving error" to quickly zero in on the most informative subset of features.
As opposed to typical data mining tools, Automate Shaving offers more than the typical variable importance list. Additionally, the analyst is provided with a full set of variable importance subsets/variations enabling the analyst to quickly optimize/select the final variable list and eliminating the burden of repetitive testing. Expert modelers typically devote a lot of time and effort to optimizing their variable importance list; Automate Shaving automates this process.
Example 2: Fraud Detection
Automate Priors
In typical fraud detection applications the analyst is concerned with identifying different sets of rules leading to a varying probability of fraud. Decision trees and TreeNet gradient boosting technology are typically used to build classification rules for detecting fraud. Any classification tree is constructed based on a specific user-supplied set of prior probabilities.
One set of priors will force trees to search for rules with high levels of fraud, while other sets of priors will produce trees with somewhat relaxed assumptions. To gain the most benefits of tree-based rule searching approaches, analysts will try a large number of different configurations of prior probabilities. This process is fully automated in Automate Priors. The result is a large collection of rules ranging from extremely high confidence fraud segments with low support to moderate indication of fraud segments with very wide support. For example, you can identify small segments with 100% fraud or you may find a large segment with a lesser probability of fraud, and everything in-between.
Example 3: Market Research - Surveys
Automate MVI (Missing Value Indicators)
In any survey, a large fraction of information may be missing. Often, the respondent will not answer questions either because they don't want to or are unable to do so. In addition to Salford Systems' expertise in handling missing values, a new automation feature allows the analyst to automatically generate multiple models including: 1) a model predicting response based solely on the pattern of missing values; 2) a model that automatically creates dummy missing value indicators in addition to the original set of predictors; and/or 3) a model that relies on engine-specific internal handling of missing values.
Example 4: Engineering Application
Automate Target
In a modern engineering application, as part of the experimental design, a large collection of sampled points may be gathered under different operating conditions. It can be challenging to identify mutual dependencies among the different parameters. For example, temperatures could be perfectly dependent on each other, or could be some unknown functions of other operating conditions like pressure and/or revolutions. Automate Target gives you powerful means to automatically explore and extract all mutual dependencies among predictors. By the word "dependencies," we mean a potentially nonlinear multivariate relationship that goes way beyond the simplicity of conventional correlations. Furthermore, as a powerful side effect, this Automate provides general means for missing value imputation, which is extremely useful to support those modeling engines that do not directly handle missing values.
Example 5: Web Advertising
Automate Sample
In an online ad placing application one has to balance the amount of data used vs. the time it takes to complete the model building. In web advertising there can be virtually an unlimited amount of data. So while ideally you would wish you use all available data, there is always a limit on how much can be used for real-time deployment. Automate Sample allows the analyst to automatically explore the impact of learn sample size on model accuracy. For example, you may discover that using 200,000,000 transactions provides no additional benefit in terms of model accuracy compared to 100,000,000 transactions.
Example 6: Microarray Application
Automate TARGETSHUFFLE
Microarray research datasets are characterized by an extremely large number of predictors (genes) and a very limited number of records (patients). This opens up a vast area of ambiguity resulting from the fact that even a random subset of predictors may produce a seemingly good looking model. Automate TARGETSHUFFLE allows you to determine whether the model performance is as accurate as it appears to be. Automate TARGETSHUFFLE automatically constructs a large number of auxiliary models based on randomly shuffled target variables. By comparing the actual model performance with the reference distribution (no dependency models), a final decision on model performance can be made. This technology could result in challenges to some of the currently produced papers in microarray research. If a dataset with deliberately destroyed target dependency can give you a model with good accuracy, then relying on the original model becomes rather dubious.

User Guide
The Salford Predictive Modeler® Software Suite
Core components include CART®, MARS®, TreeNet®, Random Forests®, and Generalized PathSeeker
CART® Classification and Regression Trees
This guide describes the CART product and illustrates some practical examples of its basic usage and approach.
Welcome to CART, a robust decision-tree tool for data mining, predictive modeling, and data preprocessing. CART (Classification and Regresion Trees) automatically searches for important patterns and relationships, uncovering hidden structure even in highly complex data. CART trees can be used to generate accurate and reliable predictive models for a broad range of applications from bioinformatics to risk management and new applications are being reported daily.
Salford Systems' CART is the only decision-tree system based on the original CART code developed by world-renowned Stanford University and University of California at Berkeley statisticians Breiman, Friedman, Olshen and Stone.
[j#423:1602]
MARS® Multivariate Adaptive Regression Splines
This guide provides a brief introduction to MARS.
MARS, is considered the world’s first truly successful automated regression modeling tool. Multivariate Adaptive Regression Splines (MARS) has become widely known in the data mining and business intelligence worlds only recently through our seminars and the enthusiastic endorsement of leading data mining specialists. MARS is an innovative and flexible modeling tool that automates the building of accurate predictive models for continuous and binary dependent variables. It excels at finding optimal variable transformations and potential interaction within any regression-based modeling solution and easily handles the complex data structure that often hides in high-dimensional data. In doing so, this new approach to regression modeling effectively uncovers important data patterns and relationships that are difficult, if not impossible, for other methods to reveal.
[J#416:1602]
TreeNet® Stochastic Gradient Boosting
This guide describes the TreeNet product and illustrates some practical examples of its basic usage and approach.
TreeNet is a revolutionary advance in data mining technology developed by Jerome Friedman, one of the world's outstanding data mining researchers. TreeNet offers exceptional accuracy, blazing speed, and a high degree of fault tolerance for dirty and incomplete data. It can handle both classification and regression problems and has been proven to be remarkably effective in traditional numeric data mining and text mining.
[J#424:1602]
Random Forests®
This guide provides an introduction into RandomForests Modeling Basics.
This guide describes what’s under the hood, beginning with why RandomForests’ engine is both unique and innovative. Because RandomForests is such a new tool, we assume no prior knowledge of the adaptive modeling methodology underlying RandomForests. To put this methodology into context, the first section discusses the modeler’s challenge and addresses how RandomForests meets this challenge. The remaining sections provide detailed explanations of how the RandomForests model is generated, how RandomForests handles categorical variables and missing values, how the “optimal” model is selected and, finally, how testing regimens are used to protect against overfitting.
[J#426:1602]
GPS Generalized Path Seeker
This guide provides a brief introduction to GPS as well as a guide insight for model interpretation.
GPS or Generalized PathSeeker is a highly specialized and flexible regression (and logistic regression) procedure developed by Jerome Friedman (the co-creator of CART and the developer and inventor of MARS and TreeNet, among several other major contributions to data mining and machine learning). GPS is a "regularized regression" procedure meaning that it is designed to handle modeling challenges that are difficult or impossible for everyday regression.

All Salford apps are very CPU intensive, so more memory and a faster CPU are always helpful.
Licensing Application
The Salford Predictive Modeler uses a system of application system ID and associated unlock key. When installation is complete, the user will need to email the application "system ID." This system ID is clearly displayed in the License Information displayed the first time the application is started. You can alternatively get to this window by selecting the Help->License menu option.
Method 1: Fixed License
With a fixed license, each machine must have its own copy of the licensed program installed. If your license terms permit more than one copy, then the license must be activated on each machine that will be used.
Method 2: Floating License
This method of licensing your program is used if you intend the program application to be used by more than one user concurrently over a network. A floating license tracks the number of copies "checked out." When that number exceeds your license terms, a message is provided informing the user "all copies are checked out." The licensed program may be installed on a machine that each client machine can access. Machines that are not connected to the network must be issued a fixed license (Method 1 above).
A floating license is particularly useful when the number of potential users exceeds the number of seats specified in your license terms.

Testimonials
Rawa Shamroukh, Union Bank, Vice President / Senior Strategic Modeling Manager, Predictive Modeling Department
Using Salfords’ data mining Software TreeNet and CART for the last 8 years, Union Bank has developed multiple in-house statistical models for the various business units within Retail Banking. These tools have greatly expanded our ability to synthesize massive amounts of data quickly, reduce our modeling turn around-times, and mainly produce the most robust predictive models in terms of accuracy and performance. The main benefits from these tools from the bank’s perspective are time savings, Productivity increase, superior analytics, and affordable tools. Treenet and CART provided significant advantages and established a new paradigm for certain modeling challenges within our department. Benefits were obtained along each step of the overall data mining process from data processing to model development and implementation. It demonstrates remarkable performance for both regression and classification models. When I first started using Treenet for logistic Regression Modeling, I always used to develop a parallel model using basic SAS. Treenet kept outperforming SAS logistic regression models over and over. In my opinion, the most amazing features in these tools are their automatic handling of variables selection, collinearity, data transformation, outliers, and many more. In addition, you can have on-the-spot model assessment by generating immediate Gain / Lift charts, ROC measures, Train/ test comparison, Misclassification / prediction success, etc. Using these tools, you will have the options to deploy your final model in a SAS environment or a SQL environment since they automatically translates your model into SAS codes, C codes, or PMML codes. I have used Treenet in various applications. To name few: Attrition models, Behavior scoring models, Operation losses models, Overdraft models, Uncollected funds models, Fraud models, etc.

In the Decision Analytics practice of EXL Service we build many predictive models for our clients representing a wide range of industries, levels of complexity and application environments. CART and MARS have been standard tools that our resources are trained on and apply in model development. I personally have been using Salford Systems products for nearly 8 years and I believe will continue using them for the foreseeable future. I have mostly used CART and sometimes MARS, and in recent years also tried Random Forests and TreeNet. All of the products offer an intuitive GUI interface and versatility but for me personally CART would be the winner.
When it comes to decision trees there are other options in the market but none has come close to CART in terms of rich functionality, intuitive ease of use and affordability. These are reasons why I continue recommending it to our modeling resources. There several ways we take advantage of CART features. First of all, it is quite easy and quick to build a CART tree with decent predictive power and which you can also explain to business users - something that's very important to our clients. Besides building tree models we often use CART to quickly derive insights about the data by building a preliminary tree and exploring the variable importance list, important nodes and making sense of individual variables. I find the data exploration functionality incredibly valuable especially when you have hundreds or thousands of variables. CART and MARS have also helped us to create composite variables that we have used in regression models - another very useful feature we frequently use. CART also comes in handy to quickly identify segmentation strategies in complex scenarios. All of these features make CART a very important tool in our model development toolkit and help us bring value to our clients.

I am conducting a project about GIS, in which many data analysis are needed. Lacking useful tools, our project made slow progress. In an accidental chance I got a TreeNet trial version and it shocked me with its powerful capabilities of data analyzing, friendly user interface and most important of all, accuracy. After using it we got many benefits from it during our research and our project had gone much faster.
In many features of TreeNet, we like most is plots which offers graphs displaying after building model. This feature is especially useful to us which provides the most visual and easy way to find shortcomings and make improvement of the model. We like the multiple model setting up ways as well, it’s flexible and covers most aspects of our research.
What attracts me most is the amazing speed of TreeNet. We have used some other software before using TreeNet. None of them could build a model in such a short time. What’s more, using TreeNet, the painstaking procedures of data preprocessing are saved, it greatly accelerated our research. Since our data contains over 100 million of variables, using common software, it takes weeks to get a result of analyze. However, by using TreeNet, it takes just a couple of days.
In addition, the most important is the accuracy. Due to the defects of sampling stage, there are some noisy variables in our data, which brings instability to our model. By using TreeNet, we got more stable model of our research than by other tools. What’s more, the model we built by TreeNet could be repeated and verified.
As to ROI, I cannot say how much money we have saved by using this tool, but we did consider to buy a high performance computer(about 5000 US dollars)to assist our research. After using the software, we decided to postpone that purchasing.
We are getting to use TreeNet just a few months , but we really impressed by its powerfulness. We know we are using just a few common features, a lot of powerful features are still waiting for us to learn.

I have 6 years using SAS and other statistical software to conduct academic and business projects. I started using SPM to build predictive models in May 2014. Our team mainly uses SPM TreeNet to build models for direct mail campaigns. I think the SPM software (Salford Predictive Modeler) is S.P.M. - SMART, PRODUCTIVE and MANAGEABLE.
